Computer artwork of the molecule of Phenylalanine,an essential amino acid. It cannot be synthesised by humans and is instead sourced from the diet. It is a neutral,non-polar amino acid and a precursor for tyrosine,another amino acid involved in the production of the neurotransmitters norepinephrine (noradrenaline),dopamine,and epinephrine (adrenalin). Atoms are represented as colour-coded spheres: carbon (black),hydrogen (white),nitrogen (blue) and oxygen. Illustration | |
